T1566.002 Spearphishing Attachment
T1059.001 PowerShell
The PDF contains a heuristic firing for a malicious redirector link, pointing to 'https://ttraff.cc/pify?keyword=cauchy+schwarz+inequality+problems+pdf'. Additionally, it exhibits characteristics of a PDF link farm, with numerous external links, including 'https://cdn.shopify.com/s/files/1/0428/1267/0111/files/gta_vice_city_crackeado.pdf'. The document body, though heavily obfuscated, contains references to these URLs, suggesting a social engineering attempt to drive traffic to malicious infrastructure.
Heuristics 3
-
PDF links to known malicious redirector infrastructure critical PDF_MALICIOUS_REDIRECTOR_LINKPDF contains a clickable URI to redirector infrastructure used by a known malicious PDF SEO/adware delivery campaign. These documents typically rely on user interaction and redirect chains rather than a PDF parser vulnerability.
-
Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARMSmall PDF contains many clickable external PDF links, mostly clustered on one host. This matches generated SEO/link-farm PDF carriers used to route users into malicious or unwanted-software delivery chains, rather than a normal document citation pattern.
-
